Issue: The bike ride is extremely slow, as if I am walking slowly. I have read and tried some of your suggestions in past posts but still having issues. (e.g. ensuring tire pressure is adequate, trying loosening up/tightening the trainer’s magnetic wheel) I will be as detailed as I can. The Zwif…

Where exactly did you place the speed sensor? When you ride is your rear tire moving at a normal speed (faster and slower) depending on how you pedal or is it Ike you are pedaling always in sand?

The speed sensor is right on the rear tire’s axle (around the wheel hub). No, it feels all right, doesn’t feel like I am pedaling in a sand.

Ok, thank you. I know that since I have a dumb trainer, my power in watts is capped but the speed that I get in the game really ruins the Zwift experience for me.

I think my issue may have been solved. I made sure the rear wheel was centered on the magnetic wheel and played around with the pressure it was putting on the wheel itself. I rode for few minutes and then toward the end of the ride, it picked up speed.

Can you keep your bike on the trainer but decouple the resistance? So you are just spinning the rear wheel and if Zwift picks up that sensor it should calculate higher watts and in turn higher speed. I have never done this test myself but I do know that the tire against the trainer pressure is impor…

Thank you, Bob. So, I removed the resistance completely from the rear tire. The watts went up to 90~100 and it picked up little bit speed but it felt more like I was in sand. Speed was little bit faster. I will play around with resistance.

Can you try to remove your cadence sensor, only pair the speed sensor, sometimes they get mixed up. [image] arinmsn: it felt more like I was in sand With no resistance your rear wheel will be spinning very fast in air. if it feel like sand then you need to check that your breaks are not rubb…

[image] arinmsn: Also: An quick-release axle was included with trainer. I was not able to remove my bike’s rear tire axle. It’s not a quick-release type. Has anyone had this issue (not being able to remove axle and just placing the rear tire as it is on the trainer? ) Check the documentation …

Gerrie, thank you. Removed the cadence sensor. When I was trying to remove the rear tire axle, I must have tightened the rear brakes. I have loosened it a bit while removing all resistence. The speed was a little bit improved but it was the same as you described, spinning fast in the air. Perhaps I …
